This is not quite correct.

Capabilities are used to express functions that can be performed. An NSF
may have multiple Capabilities. Capabilities are first **registered** using
the Registration Interface. I would have expected this model to do that.

I find this confusing. Any YANG module should be able to get and set
information. Assuming that "query" means "get" here, I see no reason to
have a separate YANG module for that.

I do, however, see a need for a separate YANG module for
**registering** the capability information.

Note: please be careful in your wording (i.e., "model" vs. "module").

regards,
John

[I2nsf] relationship between draft-hares-i2nsf-capability-data-model-03 & draft-kim-i2nsf-nsf-facing-interface-data-model-02? (was RE: Request for Timeslots in I2NSF WG Meeting

[Linda Dunbar]

Paul and Sue:

You requested slots for both draft-hares-i2nsf-capability-data-model-03 & 
draft-kim-i2nsf-nsf-facing-interface-data-model-02.

The abstract of draft-kim-i2nsf-nsf-facing-interface-data-model-02 stated that 
the draft defines the data model for network security functions), such as 
network security control, content security control, and attack mitigation 
control,..

The draft-hares-i2nsf-capability-data-model-03 has specified the High-Level 
YANG for Network Security Control, Content Security Control and Attack 
Mitigation Control.

How are those two drafts related?  I have a vague memory that those two drafts 
are to be merged, are they?

Thank you very much,

Linda
